These tiles came from the same "rescue" as the floral trim tiles I've posted earlier. In addition to amazing decorative tiles Malibu Potteries (1926 - 1932) produced a number of solid tiles in all kinds of shapes. The Potteries targeted builders and architects, and I believe most of the tiles I have are meant to be bathroom tiles. The glaze colors (blue, turquoise, jade) and quality (matte and glossy) are what makes these stand out.

There are also a few really nice blue pillow tiles in two different sizes that are documented on page 66 of the California Tile, The Golden Era 1910-1940 (vol. 2).

These tiles have survived two fires and some of them have been previously installed. Some have chips and attached mortar, while others are in excellent condition.
